4.2 Denmark

4.2.1 GAS TRANSMISSION AND

DISTRIBUTION NETWORK DEVELOPMENT The natural gas transmission network covers most of Denmark and runs a total of approx. 950km in length. The oldest sections were built in the 1980s and the most section in 2013, when a project co-financed by the EU resulted in a doubling of the connection to Germany and a compressor station to provide the required pressure. A maintenance program ensures that the system will be able to remain safe and op- erational for decades to come. The central control room is located by the compres- sor station in Egtved (see figure 4.2) and is always staffed. The control centre facili- tates the supply of gas from the Danish part of the North Sea and from Germany as well as the export to Germany and Sweden. The system is furthermore linked to two storage facilities. Both the transmission system and the storage facilities are owned by Energinet.dk.

Keys Cross-border EU or non-EU export. Under construction or planned Cross-border interconnection point within EU and with non-EU third country (export)

The gas reaches the majority of the customers through 17,000km of distribution pipelines owned by four distribution companies, which are among the active players on the retail market. In 2016, Energinet.dk has bought one of the distribution com- panies. Energinet.dk is also in the process of buying the offshore natural gas pipe- lines from DONG together with other assets. Currently, a feasibility study (partly financed by the EU) conducted by Energinet.dk and GAZ SYSTEM (Polish Gas TSO) is investigating the basis for linking the Danish and Polish gas markets through a new transmission line (Baltic Pipe) with PCI status. With respect to this, it is being studied how the Danish and Norwegian gas systems could be linked in order to increase security of supply for the Danish and Polish mar- kets. The study will be concluded at the beginning of 2017.
